xfrm: support 'multicast' attribute on interfaces

You shouldn't need the overhead of GRE just to add multicast
capability on a point-to-point interface (for instance, you might
want to run mDNS over IPsec transport connections, and Avahi
requires IFF_MULTICAST be set on interfaces, even point-to-point
ones).

Borrowed heavily from:

    b3c9321b9e gre: Support multicast configurable gre interfaces
